Some call Ireland the island of forty shades of green. The winds, the rain, and the warming influence of the Gulf Stream all contribute to the year-round lushness. It also contributes to the year-round diet of their grass-fed cows who in turn produce the sweetest, richest milk in the world. It's the reason Kerrygold's unsalted butter tastes silkier and creamier and glows a healthy, golden yellow like the sun.
